Why is GDB throwing an error about a missing raise.c file even though I'm catching an exception?

GDB Error: Missing raise.c File

When running GDB to debug a program, users may encounter an error message complaining about the missing raise.c file. This occurs despite catching an exception. To resolve this issue, it is necessary to prepare GDB for full-source-code debugging of the C library.

1. Install Debuginfo Version of Libc6:

   If not already installed, install the debuginfo version of libc6 using:

2. Prepare Package System:

   Ensure the package system can process source code packages by:

   • Installing dpkg-dev: sudo apt install dpkg-dev
   • Checking for deb-src lines in /etc/apt/sources.list (unycomment if necessary)
   • Updating the repositories: sudo apt update

3. Download Source Code:

   • Create a directory (e.g., /opt/src)

   • Download the source code for the installed C library version:

   • Note the directory name (e.g., /opt/src/glibc-2.23)

4. Configure GDB:

   Determine the directory where GDB expects the source code by running (gdb) info source within GDB. Specify the correct directory path using (gdb) set substitute-path or move the source code to the expected location.
